Calibration cube

This is a 20x20x20 mm calibration cube printed on a Bambu Lab 3D printer, used to assess overall print quality and fine-tune settings.

The cube has clearly visible engravings of the letters "X," "Y," and the "bambu" logo on the side walls, making it easy to check dimensional accuracy and axis alignment. The top surface is open with triangular cutouts, making it easy to observe layer consistency and bridging efficiency. A cone in the center allows you to determine the quality of the layer stacking.

This type of test print is commonly used to verify:

dimensional accuracy (whether the cube is exactly 20 mm on all sides),

surface smoothness,

layer adhesion,

edge and corner sharpness.

Based on the results, you can adjust settings such as nozzle temperature, print speed, cooling, and extrusion multiplier for a smoother and cleaner finish.
